उत्तर

Steps for construction:

  1. Draw concentric circles of radius 4 cm and 6 cm with centre of O.
  2. Take point P on the outer circle.
  3. Join OP.
  4. Draw perpendicular bisectors of OP where M is the midpoint of OP.
  5. Take a distance of a point O from the point M and mark arcs from M on the inner circle it cuts at point A and B respectively.
  6. Join PA and PB.
  7. We observe that PA and PB are tangents from outer circle to inner circle are equal of a length 4.5 cm each.
